SoTransformBoxDragger is a composite dragger shaped like a box with small cubes at the corners. Click and drag any of these cubes to scale the box uniformly. Drag any edge of the box to rotate the whole dragger about its center, along an axis parallel to that edge. Pick any face of the box for 2D translation in the plane of that face.

Although the box looks just about like a wireframe cube, it is composed of many different simple draggers arranged in a composite assembly. When one part is dragged, the transformBox makes sure they all move together. Each of the parts of the box is a different dragger with the default geometry changed. The faces of the box are SoTranslate2Draggers, the edges are SoRotateCylindricalDraggers, and the cubes are an SoScaleUniformDragger. Drag them and the dragger will update its translation, rotation and scaleFactor fields to reflect the changes. As with all draggers, if you change the fields the dragger will move to match the new settings.

Remember: This is not an SoTransform!. If you want to move other objects with this dragger, you can either:

[a] Use an SoTransformBoxManip, which is subclassed from SoTransform. It creates one of these draggers and uses it as the interface to change its fields. (see the SoTransformBoxManip man page).

[b] Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation node.

You can change the parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoTransformBoxDragger class. They are detailed in the Dragger Resources section of the online reference page for this class. You can make your program use different default resources for the parts by copying the file /usr/share/data/draggerDefaults/transformBoxDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.


SoSFRotation rotation
Orientation of the dragger.

SoSFVec3f translation
Position of the dragger.

SoSFVec3f scaleFactor
Scale of the dragger.



static const SoNodekitCatalog * getClassNodekitCatalog() const
Returns an SoNodekitCatalog for this class

static SoType getClassTypeId()
Returns type identifier for this class.

Dragger Resources

.in 0n+.5i

Resource: transformBoxScalerScaler
.in 0n+.5i
Part: scaler.scaler
Appearance: Eight small white cubes at the corners of the box
Description: Picking this initiates uniform 3D scaling of the dragger.

.in 0n+.5i
Resource: transformBoxScalerScalerActive
.in 0n+.5i
Part: scaler.scalerActive
Appearance: Yellow version of the regular scaler part
Description: Displayed while the dragger is being scaled.

.in 0n+.5i
Resource: transformBoxScalerFeedback
.in 0n+.5i
Appearance: Empty separator
Description: Removes any feedback geometry created in the constructor of the SoScaleUniformDragger.

.in 0n+.5i
Resource: transformBoxScalerFeedbackActive
.in 0n+.5i
Part: scaler.feedbackActive
Appearance: Empty separator
Description: Removes any feedbackActive geometry created in the constructor of the SoScaleUniformDragger.

.in 0n+.5i
Resource: transformBoxRotatorRotator
.in 0n+.5i
Parts: rotator1.rotator
Appearance: Four white lines along the edges of the box
Description: Picking this begins rotational dragging. In each of the three rotateCylindrical draggers, the lines of the rotator part are oriented parallel to the axis of rotation.

.in 0n+.5i
Resource: transformBoxRotatorRotatorActive
.in 0n+.5i
Parts: rotator1.rotatorActive
Appearance: Four yellow lines along the edges of the box
Description: Displayed while the dragger is being rotated

.in 0n+.5i
Resource: transformBoxRotatorFeedback
.in 0n+.5i
Appearance: Empty separator
Description: Removes any feedback geometry created in the constructor of the SoRotateCylindricalDragger.

.in 0n+.5i
Resource: transformBoxRotatorFeedbackActive
.in 0n+.5i
Parts: rotator1.feedbackActive
Appearance: Thin purple line through center of box
Description: Displayed to show axis of rotation during rotational dragging.

.in 0n+.5i
Resource: transformBoxTranslatorTranslator
.in 0n+.5i
Parts: translator1.translator
Appearance: Invisible but pickable square surface
Description: Picking these begins 2-D translational dragging within the plane of one of the sides of the box. The invisible squares of the six translate2Draggers are arranged to form the sides of the box. The squares are easy to discern, although rendered as invisible; they are bounded by the lines of the rotational dragger parts.

.in 0n+.5i
Resource: transformBoxTranslatorTranslatorActive
.in 0n+.5i
Parts: translator1.translatorActive
Appearance: Invisible square surface
Description: Shown during 2-D translational dragging.

.in 0n+.5i
Resource: transformBoxTranslatorXAxisFeedback
.in 0n+.5i
Parts: translator1.xAxisFeedback
Appearance: Short thin purple line
Description: Only shown if dragger is moving and the axis is a permissable direction of motion. When pressing <shift>, motion is constrained, and this is displayed only if the primary motion is in the X direction.

.in 0n+.5i
Resource: transformBoxTranslatorYAxisFeedback
.in 0n+.5i
Parts: translator1.yAxisFeedback
Appearance: Short thin purple line
Description: Only shown if dragger is moving and the axis is a permissable direction of motion. When pressing <shift>, motion is constrained, and this is displayed only if the primary motion is in the Y direction.
